Located within .the condenser chamber 7 is a succession of coils in the condenser pipe or tube 56 with the initial end of which the gas conduit communicates. The outlet of the condenser coil communicates with the reverse end of the conduit S with the cap 59 securedto the base 55. T he conduit 58 through said cap or head 59 forms an intercommunicating conduit between the condenser chamber 7 and the receiver.

Located within below the plane of the is a water supply head versely arranged water conduit 61 from which extends a plurality of perforated pipes or tubes 62. The pipes 62 are preferably arch-shaped as shown by dotted lines condensing coil in the top plan View 5 and are provided at their upper sides with a series of small perforations 63 through which numerous jets of water are discharged upward. It will be understood that the condenser chamber 7 is normally completely filled with water in which the condenser coils 56 are submerged. The purpose of the spray or jet head tor the cooling water is to distribute the water equally throughout the chamber 7 to secure more thorough and uniform circulation and yto further insure all parts of the condensation coil 56 being reachedv 'by the cold water circulated through the chamber 7. This cooling water' is conducted to the spray head or distributer in the bottom-of the con denser chamber 7 through a Water supply conduit 60 leading from any suitable source, such as a city water main, a tank, pump or other supply means. The supply of cold water is circulated through the `condenser chamber 7 aroundA the condenser coils 56 thence from the' chamber 7 through aconn duit 39 before mentioned, which leads from the chamber 7 to the annular or water jacket 35 of the cylinder 20. The water having passed through the chamber about the cylinder and through the chamber 36 in the head 37, is ,dischargedY through the water outlet conduit 38, either as waste water or is conducted baclcto thetank, well, or other source of supply.-
